Current dts files with 'grf' nodes are manually verified.
In order to automate this process grf.txt has to be
converted to YAML.

Most compatibility strings are in use with "simple-mfd" added.

Add description already in use:
"rockchip,rv1108-pmugrf", "syscon"

Add new descriptions for:
"rockchip,rk3568-grf", "syscon", "simple-mfd"
"rockchip,rk3568-pmugrf", "syscon", "simple-mfd"

Signed-off-by: Johan Jonker <jbx6244@gmail.com>

Changed V3:
  remove select
  change unevaluatedProperties
  add separate schemas for each 'if' subset

Changed V2:
  add rockchip,rk3328-grf-gpio.yaml
  rename grf-gpio nodename

Sorry, but by separate I meant different files. But you don't *have* to 
do that.

There's not really any point to using '$defs' unless you have 2 or more 
references to them.

Hi Rob,

I've tried without '$defs' and I can't get dt_binding_check error free with:
allOf:
  - if:
      [etc..]
  - if:
      [etc..]
That's why this construction.
Could you test with patch below.
Please advise.

Johan

There's a requirement that all the properties be defined at the top
level. If 'unevaluatedProperties' was actually implemented, we
wouldn't need that. So you need something like this:

-* Rockchip General Register Files (GRF)
-
-The general register file will be used to do static set by software, which
-is composed of many registers for system control.
-
-From RK3368 SoCs, the GRF is divided into two sections,
-- GRF, used for general non-secure system,
-- SGRF, used for general secure system,
-- PMUGRF, used for always on system
-
-On RK3328 SoCs, the GRF adds a section for USB2PHYGRF,
-
-ON RK3308 SoC, the GRF is divided into four sections:
-- GRF, used for general non-secure system,
-- SGRF, used for general secure system,
-- DETECTGRF, used for audio codec system,
-- COREGRF, used for pvtm,
-
